That sounds like me. I sometimes go to the store with a meticulously prepared list and often forget SOMETHING from that list. Though I've never gone with a list for two things and forgetten one of the items!

My major problem is coming back with things never on the list in the first place. My husband is very good about bringing back ONLY what's on the list.

He needs to use my new memory system. Basically, you associte painful thoughts to the items you are trying to remember. then you peg those memories to parts of your body, starting at your toes. For example, Water Jug: Imagine yourself droppping a full water jug on your toes. The pain is intense and the water is pouring out all over the floor making it slippery, and you fall.

For bread, you could imagine rubbing slices of bread on your thighs. Imagine the scratchy feeling of dry bread being rubbed.
